Abu Dhabi's Capital Gate Tower Tops Out at 525 Feet
November 17, 2009
Dhabi's Capital Gate, which leans 18 degrees-14 degrees more than
the Leaning Tower of Pisa, recently topped out its central core
and reached its final height of 525 feet. The project is being developed
by Abu Dhabi National Exhibitions Company (ADNEC) and has been designed
by global architects RMJM, with a North American division headquartered
in New York (CLICK

stands as the focal point of the Capital Centre development, an
AED8 billion (U.S. $2 billion) business and residential micro city
being constructed around the thriving Abu Dhabi National Exhibition
"Capital Gate is an excellent example of what can be achieved
when vision, creativity, design and engineering combine effectively
with a partnership approach among team members. I am pleased at
the steady progress being made on Capital Gate and would like to
commend everyone involved in bringing this amazing and complex project
to life. We look forward to working with RMJM, and Al Habtoor, the
contractors of Capital Gate, to ensure the development is delivered
to the people of Abu Dhabi over the course of the next year,"
said Simon Horgan, Group CEO of ADNEC.
"Topping out the core is a major milestone to achieve. We still
have challenges to face, but with the meticulous planning and recording
that we have implemented throughout the construction, the pathway
to successful completion is very much in sight," says RMJM's
associate director, Tony Archibold, who explains that the tower's
core slants in opposite direction to the lean of the building, straightening
as it grows. "This has never been attempted anywhere in the
world before," he said.
Due to its unique shape, Capital Gate, which features glass supplied
by Cardinal (CLICK

deep concrete base with a dense mesh of reinforced steel. The tower
comprises a complex steel diagrid, which sits above an extensive
distribution of 490 piles that have been drilled 100 feet underground
to accommodate gravitational, wind and seismic pressures caused
by the lean of the building. The angles and dimensions of the building
have been measured and designed meticulously to ensure that each
individually shaped diagrid accurately defines the shape of this
